' GAS PRODUCER Filed Feb. 6, 194a v INVENTOR. MARC F CHARRIER Patented Feb. 22, 194 9 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to the production of gas for illumination, power and other purposes, and it pertains more particularly to the generation of gas from straw, corn-(robs, weeds, husks, hulls, peat and other suitable waste materials. The gas is generated in a comparatively small apparatus, such as may be employed advantageously on farms and in other places where operation must be easy, and output small, compared with the mass production required for large cities.

With generators commonly so used. it has been found that the expenditure of fuel has been too great for the results obtained, and thus the product has been too costly in communities where fuel is scarce or its cost too high.

It is an object of the invention, to provide a generator so formed that the gas producing mass is quickly and uniformly brought throughout to the degree of temperature required for its destructive distillation, and evolution of all available gas therefrom, with the result that economy of fuel and time is attained.

A further object of this invention is to provide a gas producer with superimposed bank of fire flues, the lower bank, besides transmitting the flames, also acts as a support for the waste matter used in generating the gas.

Other novel features of the invention will ap pear from the following description, when read in connection with the accompanying drawing.

In the drawing:

Fig. 1 is a longitudinal section of the gas producer.

Fig. 2 is a section taken on line 22 of Fig. 1.

Fig. 3 is a modified form of producer.

The gas producer consists of an outer casing is), which rests on the ground or a base H, with a shell 52, resting on said base. The casing has a front wall !3, and a rear wall It, and is covered with insulating material 55.

Within the casing 59, there is a retort Iii, properly supported. on an inverted arch ii. and on the bent in proportions of the outer shell #2. This retort 5%, comprises a drum l8, with end walls 59, and welded thereto. Through the retort Hi, there extends a lower bank of flues 2 l, which are substantially the center of the retort, and close together so as to retain the waste products. Through the upper portion of the retort l5, there ex e An o-iitake 23 is connected with the retort from which the generated gases are abstracted by means of pipe 2 The oi -Stake 23. is provided with a safety valve, or weighted cover 25, hingedly aflixed at 25.

nds a second bank of flues Z2.

Under the retort [6, there is provided an ordinary fire box 2i, with a grate 28, and ash chamber 29.

The retort I6, is provided with two openings 30, and 3|, which project into the front wall It. These opening are used for inserting the waste material for generating the gas, as straw or other vegetable matter. The openings are kept closed by means of doors 32, and 33, operated in any desired maner.

The fire box 21, is provided with a door 34, and the ash chamber with a door 35.

Between the front wall [3, and the retort Hi, there is provided a baffle 36, which extends through the width of the retort it.

A damper 31, set between the retort l5, and the rear wall 54, is adapted to control the flames so that they travel directly to the smokestack 38, or through the flues 21.

A pipe 39, at bottom of the retort i6, is provided and is used for removing sediment etc.

In the operation of the gas producer, the straw, peat or other vegetable matter is placed on the bottom of the retort I6, through the door 33. Another portion of the same material i inserted through the door 32, and placed on the smoke fines 2 l, which act as a grate. The fire in the fire box 2'1, heats and decomposes the matter in the bottom of the retort, and the flames passing through the fines 21, heats and decomposes the matter placed theeron.

The gases generated in the retort on rising upwardly are superheated by the flues 22, causing the separation of any substances carried by the gases generated. The gases are then led off by means of a pipe 24, to the separator, purifier and expansion chamber and ready for use.

In Fig. 3, a modified gas producer is shown. Here the casing Gil. has two boxes ii and 52, in which the waste matter is placed. through doors at, and M. A fire box i5, and a fire box door 56 is provided. An ash door ii, through which the ashes are removed. Bail'le plates 48, and 49, direct the flames in a tortuous path so as to thoroughly heat the boxes. Gas oiitake pipes 55, and ti, are connected to the boxes Ill, and 42, and lead off to the separator, purifier and expansion chamber and ready for use.

As various changes may be made in the above embodiment without departing from the spirit of the invention, it is to be understood that all matter herein is to be interpreted as illustrative, and not in a limiting sense.

What I claim is:

1. In a gas producer, a fire box, a retort above of access to each chamber, aset of combustion flues, said flues forming the division between the generating chambers, and arranged to function as a grate for the upper chamber, and a second set of fiues passing through said retort near the top thereof for superheating the generated gases.
